New this month Continuity mistake: When Drebin first meets Ludwig, you see the shelf of vases. To the left of that is the fancy painting. However, when Drebin accidentally sets fire to the office, he rushes to the shelf to catch the vases as they fall. He then look to his right to see the flames getting close to the painting. He moves to his right (pulling down the shelf of vases in the process), takes the painting off the wall, and impales it on the plant. It should've been the other way around. Drebin should've looked and moved to his left instead of his right.
Factual error: At the onset of the baseball game, take a look at the Angel's catcher as Mariner Jay Johnstone steps up to bat. You will see he is wearing just a standard baseball hat under his catcher's helmet. MLB rules requires some form of certified (protective inside and out) plastic helmet for catchers, and thus this would not be allowed. (01:07:35)
Other mistake: Pay attention to one of the early innings of the baseball game as one of the Angels players hits a home run. Though probaby intentionally set up this way as to avoid any problems of "logo patents" and such with the real life MLB California Angels team, he is wearing a helmet without the team logo on it.

Trivia: There is a trailer to this movie with an additional gag. After Ludwig has demonstrated his image of an ideal assassin to Papshmir, he sits down with the revolver used in the demonstration which had turned out to be empty. In the trailer shot (in a closeup of Montalban) the gun unexpectantly goes off.
